Anybody ever try to get the temperature of the air blowing out of your pellet stove??

350 ish. I checked it quickly once.
I have a Harman Accentra - I measure the temperature a lot because its taught me that when its clean, it burns much hotter. I give mine a good cleaning every 10-14 days. I think the air-flow is paramount. When clean I burn at 230-240'F and when its dirtier it is around 180'F.
Stove settings? Pellets you were burning?
MWP blend 218F
I have a thermostat hooked to my Harman so the different heat output between the different pellet brands does not affect my actual room temp.
My reading on 7.
On heat range 9
200 -240'ish on setting 4 of 5 with Vermont softwoods or some of the other high quality pellets. 180 on setting 3 of 5. I can get 180-200 with just about any pellet I've tried so far. It's very hard to measure with an IR gun as emmisivity of the surface (color and texture) affects the reading and you're not measuring the air temp, you're measuring the stove surface temp (plus some of what's behind the grating). I have been using a meat thermometer but my thermocouples should be here next week. Time to wire up this stove for some R&D.
This is reading surface temp. Not air temp.
Yeah. Surface temp is much more variable than Air.
I measure with a K-type thermocouple. I always do a 5 bag (or more run) all my Settings are always the same. Run on Low with feed gate wide open (Quad and Heatilator thing) and take an average.
That said, 220*-240* is a good average (depending on pellet)
280-300 degrees running Somersets and stove on power level #3 (medium)
just reread post. My original post was exhaust temp. My air coming off the heat exchanger is about 150 to 170. On setting 3 of 6
I would a though the harman would be closer in temps due to the ESP and its smarter controller. Guess not and thanks for sharing.[/quote]
